Electronics International MVP-50P - Manual (Page 67)

Flaps:
Analog input signals are calibrated using the “Flaps, Trim and Special Function Calibration” screen.
Annunciators:
The MVP-50x will display annunciators activated by digital input signals routed into a Temp or Resistive
Fuel Level channel on the EDC. An annunciator for landing lights, nav lights, boost pump, door or
canopy latch, deicing, warning indications, chip detect, door seals, bleed air, step status, FADEC out-
puts, ignition status, faults, ATR, switch settings and many more status indications may be displayed on
the MVP-50x.
Date, Local Time and Zulu Time:
When the MVP is off, these functions are kept alive via the MVP's backup battery.
Engine Hours and Tach Time (MVP-50P):
Engine Hours signify the time the engine has been operating (RPM above 350). Tach Time is the time the
engine was operated above 1190 RPM. When the MVP is off, these functions are kept alive via the
backup battery. In order to protect from losing these values (in case of a battery failure), values are
saved to Flash Memory at the end of each flight.
Engine Hours and # Cycles (MVP-50T):
Engine Hours signify the time the engine has been operating above an N1 setting. number of cycles
increments when N1 goes above a setting and arms for the next count when N1 drops below a setting.
These settings can be found in the “Engine Data ..... Setup” screen.
Flight Timer (MVP-50P):
The Flight Timer automatically starts when the RPM goes above a Start setting and stops when the RPM
goes below a Stop setting. These settings can be found in the “Engine Data ..... Setup” screen.
Flight Timer (MVP-50T):
The Flight Timer automatically starts when the N1 goes above a Start setting and stops when the N1
goes below a Stop setting. These settings can be found in the “Engine Data ..... Setup” screen.
Some Error Messages -
“COM” - If communication is lost with the EDC, after 5 seconds all functions requiring signals from the
EDC will display “EDC” for its value and an Error Message Box will be displayed.
“A-D” - If the EDC sends an error message for a specific channel, the function associated with that
channel (on the MVP) will display “A-D” for the value.
“OVR” - If a channel on the EDC is over ranged (>2.5 volts differential), an “OVR” will be displayed
for that function.
“Err” - If a capacitance fuel probe is unplugged or fails and the raw drop below 30, the fuel level will be
displayed as “Err.”
